What is the relationship between angle of incidence and angle of reflection in a plane mirror

Answers

Answer 1

In a plane mirror, the angle of equal to the angle in reflection both are identical. The law of reflection refers to this.

What is law of reflection?

The law of reflection states that when a wave reflects off a surface, the angle of incidence is equal to the angle of reflection. This law applies to all types of waves, including light, sound and water. The incident wave and the reflected wave lie in the same plane, with the angle of incidence being measured between the incident wave and the normal vector (a line perpendicular to the surface of reflection). The normal vector and the reflected wave form the angle of reflection.

how does a longshore current affect a beach?

Answers

Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. ... This process, known as “longshore drift,” can cause significant beach erosion.

is the number of paper clips in step 2 the same as the number of paper clips in step 3? why do/don't you think so?​

Answers

We can’t see steps two or three so there isn’t a way to give you the answer that you need

The number of paper clips in step 2 is the same as the number of paper clips in step 3 is a true statement, as the mass is the same for both.

What is mass?

It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.

Given:

The mas of the paper clips are the same,

Assume the number of clips in step two is x and the mass is m, the mass in the third step is the same as in step 2,

Thus, the number of clips = Total mass of paper clip / mass of one clip,

The number of clips = m / x

As we can see, if the mass is equal, then the number of clips will also be equal.

What is the volume of the water in the graduated cylinder gizmo Student Volume Lab Sheet (cm3 and mL)

Answers

Answer:

The volume of water in the graduated cylinder will be equal to the calculated volume of the sphere.

Explanation:

The volume of solid objects can be measured by completely immersing these solids in an overflow faucet filled to brim with a liquid in which the solid does not dissolve. This is known as the displacement method. When water is used, it is known as water displacement method.

In the Volume Lab Sheet, a sphere whose volume has been pre-calculated is immersed in the overflow faucet containing water. The displaced water is collected in a beaker and the volume is obtained using a 50 mL measuring cylinder.

The volume of a  sphere is calculated using the following formula:

Vsphere =  4πr³/ 3

The symbol π represents the number pi, which is about 3.14. The letter r stands for the  radius of the sphere, which is the distance from the center of a sphere to its surface. The  radius is exactly half of the diameter, which is the distance across the sphere through its center.

The volume of the water in the measuring cylinder is found to be equal to the calculated volume of the sphere. This is because an object immersed completely in a liquid displaces a volume of liquid equal to its own volume.

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.

Answers

The vertical component of the velocity at the starting is 12.5 m/s upwards.

What is velocity?

Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time.

In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

Given that  stone is thrown upwards with an initial velocity of 25 m/s at angle of 30°.

Hence,  the vertical component of the velocity in upward direction = 25 sin30° m/s

= 25 × 1/2 m/s

= 12.5 m/s.

Answers

Answer:

Weight and reaction.

Explanation:

With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.

Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.

The two forces acting on the brick are: its weight and the reaction from the scale.

Answer:

P = 500 N/m²

Explanation:

Pressure exerted at the base is the hydrostatic pressure and it is given by the formula;

P = ρgh

Where;

ρ is density = 1000 kg/m³

g = 10 m/s²

h is depth = 5 cm = 0.05 m

Thus;

P = 1000 × 10 × 0.05
